Yeah, that's a tough one Actually, I used windows xp at the same with windows 7 in my computer from time to time. And I think that's the reason of that raw part. I happened to me before and the only solution was to clean format the computer. And as you can see, it's the second time it's happening.

Concerning my problem, I will do as you've said. Thank you very much for your help. I will keep this thread posted if I reach a conclusion.

that,'s right mborner. I don't exactly remember which version it was. And it has got erasen as the time passed from COA sticker. But I did a research on google.com.tr and I found out that the same distributor who sold me the computer continues to sell it and with a windows 7 home premium 32 bit operation system. So probably that's the one for me. But I don't really know where to download it. And does the language makes a difference? Maybe mine was in turkish (sorry for my catastrophique memory).

and I know now which trial version I am runing (ultimate 64 bit but that doesn't help much)

There are no "trial" versions of Window 7 made available. When Win7 is installed without using a key, it will run for 30 days -- after which it will expire. That's not a "trial" version; that's an "unactivated" version.

Since the seller is still in business, contact them and demand the activation information. They sold you the machine; they are obligated to provide you that information.

ok thanks,
this night I was going to install a new windows 7 either home basic or home premium (downloaded all editions iso but I wasn't sure which one to start with in order to try my product key). But I'm going to start with home premium. Wish me luck

Changing product key on cloned installation: activation problem?Hi,
I had a hard drive fail on a netbook, and I put in a drive from another of the same brand that had died for other reasons. The new drive took like fish to water - no blue screens, etc. And Windows even updated, as did MSE.
But I'd like to make this machine honest by entering the Win7...

Windows Updates & Activation

Product Key Does Not Match Current Windows SKU (Foreign product key?)So short story, I work at a college tech site that fixes student and faculty computers. A foreign exchange student from Japan with a Sony Vaio (most likely from Japan as well) managed to get a virus on his computer and he was blocked off our network.
